危险源的实质内容分析

Analysis on essential content of hazard

为解决安全工作中对危险源的含义理解不一致的问题,剖析危险源的实质内容;通过分析国际标准化组织(ISO)的3个技术委员会(TC 262、TC 283、TC 292)制定的危险源相关标准,研究其中危险源定义的文字表达、标准的整体思路,结合能量学说和以往学者的研究内容,得出广泛认可的含义并归纳总结危险源的实质内容。结果表明:危险源一词来源于国际标准,实际上是事故原因;危险源的实质内容可理解为事物的危险状态、危险的物质或能量、危险的事物3种;对危险源含义的理解取决于所依据的事故致因模型。

In order to address inconsistent interpretations of hazard,its essential content was analyzed.Hazard related standards formulated by three technical committees of ISO,TC 262,TC 283 and TC 292 were analyzed,and definition expressions and general ideas in them were studied.Then,the widely recognized implications of hazard were obtained and its essentioal content was summarized based on energy theory and researches of previous scholars.The results show that the term hazard comes from international standards and it actually means causes of accidents.It can be interpreted in three ways as hazardous conditions or situations of things,hazardous substances or energy,depending on which accident causation model is used.
